问题 This question already has answers here : NSMutableArray addObject not working (3 answers) Cannot add object to an NSMutableArray array (2 answers) Closed 6 years ago . I think, I am doing a pretty basic mistake, but I am using an NSMutableArray and this somehow doesn't add the object, I'm sending it its way. I have a property (and synthesize) @property (nonatomic, strong) NSMutableArray *kpiStorage; and then: ExampleObject *obj1 = [[ExampleObject alloc] init]; [kpiStorage addObject:obj1];
